Patented Apr. 21, 1936 UNITED STATES PATENT OFFICE 7 2,037,699 PEN ANDMETHOD or MAKING run SAME Leon Hehl Ashmore, Collingswood, N. 1.,assignor to The Estcrbrook Steel Pen Manufacturing 00., Camden, N. J., acorporation of New Jersey Application July 27, 1934, Serial No. 737,3075 Claims. (Cl. 11332)' My invention relates to writing pens, and oneobject of my invention is to provide a pen with a thickened writing tipend made from blanks die-cut from metal stock having a .tumed or foldededge which forms such writing tip end.

A further object of my invention is to provide a pen made from blanksdie-cut from metal stock having a turned or folded edge in which thefolded portion may be substantially semicircularly curved and closelyengages the stock forming the body of the blank at that part'of the samewhich forms the writing point end of the finished pen.

A further object of my invention is to provide a simple method ofproducing a pen from die-cut blanks made from preformed metal stockhaving a turned or folded edge.

These and other features of my invention are more fully describedhereinafter, reference being had to the accompanying drawing, more orless diagrammatic in character, in which:

Figure 1 is a fragmentary view of a portion of flat metal stock fromwhich blanks toform my are die-cut from metal stock of this character.-

Fig. 4 is a view illustrating the manner in which blanks to form anothertype of pen aredie-cut from this metal stock.

Fig. 5 is a side view of a finished pen.

Fig. 6 is a front view of the nibs f the'finished pen on a larger scale,and

Fig. 7' is a plan view of the underside of the nibs at the writing tipend of the pen.

In carrying my invention into effect, fiat metal pen stock is preparedby folding or turning one edge of the same against itself and into closeengagement with the body of the stock, a condition that is maintained inall further use of such stock and the blanks formed therefrom in makingmy improved pens. This stock may be of any suitable metal. Fig. 1 showsa plan view on an enlarged'scale of flat metal stock from which myimproved pens may be made, and Fig. 2 .is an end view of the same. Inthese views, A represents the body of the stock, and a the turned edgeof usually disposed diagonally with respect to the longitudinal axis ofthe pen may be blanked from this stock in such diagonal relation, asindicated at 2, Fig. 4. In this blanking operation, the die. cutsentirely through the turned or folded portion at the edge of the stock.

After the blanks have been cut from the stock, they are punched at 3,and slit at 4, and then shaped or raised to the desired curvature by theusual means. They are complete pens from these operations, and they arefinished in the usual way by rumbling. The rumbling action removes anyfins left from the blanking operation. As the sides of the nibs at theforward ends of the same are on a substantially semicircular curve, allangular portions at the sides of these ends round quite readily. underthe rumbling actio'n, and the final condition of the pen issubstantially that illustrated in Fig. 5. The finished writing tip endis illustrated in Figs. 6 and 7.

A pen made in accordance with my invention from fiat metal stockpreparedwith a folded or turned edge provides initially the desiredthickvened end with a curved surface from which end the smooth writingpoint is developed, no further manipulation of such nib end beingnecessary after the pen has been blanked. By reason of this, the stepsof manufacture have been greatly reduced, my improved pen simplyrequiring blanking, piercing, slitting and raising and the usualfinishing.

When these pens are made of stainless steel, the operation of turning orfolding the edge of the stock tends to harden the same therebyincreasing the'wearing qualities of the pen. This work-hardening effectis concentrated at the point of greatest wear, to wit: the thickenedportions of the nibs which contact with the paper.

The stock from which my improved pens are made may be of any gaugecommonly employed in the manufacture of pens, and the amount of turnedor folded portion may be anything desired or necessary to form athickened end of proper dimensions.

The preparation of the fiat metal stock to provide the same with thedesired turned or folded edge is a continuous operation, and such turnedor folded edge is closely contacted with the body ends of pens and/orpen points made therefrom and permitting the production of pens and/orpen points with such thickened writing tip end from any portion of Iturned or rolled edge of the stock. p h as the work incidental toturning or folding the edge of a section of stainless steel has atendency to harden the thickened edge thus produced, the manufacture ofpens'and/or pen-points of this particular character from flat stainlesssteel stock so prepared is an important feature of my invention, sincesuch material will give a pen or pen point having a thickened writingtip end highly resistant to wear. Various modifications may be made inthe foregoing embodiment of my invention without departing from thespirit and scope thereof as set forth in the appended claims.

I claim:

1. A writing pen made from a metal blank having an end consisting of aclosely folded portion thereof; the writing tip portion of the pen madefrom such blank consisting of such closely folded end. a

2. A writing pen'made from a metal blank having an end consisting of aclosely folded portion thereof; the writing tip portion of the penconsisting of such closely folded end whose forward edge is diagonallydisposed with respect to the longitudinal axis of the pen.

3. The method of making a pen or pen point which comprises preparingflat metal stock with a turned or folded edge, cutting a blank from suchstock with the folded or turned edge portion thereof at one extremityof. the blank to' constitute the writing tip point of such pen, piercingand slitting the blank, shaping or raising the blank to pen form, andsubsequently. finishing the pen by the usual rumbling operation.

4. The method of making pens or pen points a which consists in preparingfiat metal stock with a turned or folded edge, die-cutting blanks there-'from and cutting entirely through such turned or folded edge by the dieaction whereby such folded or turned edge portion constitutes thewriting tip point of such pen, piercing and slitting the blank, shapingor raising the blank to pen form, and subsequently finishing the pen bythe usual rumbling operation.

5. In the man'ufactureof metal pens and pen 'points having a thickenedwriting tip, the steps of forming a folded or turned edgeon a strip offlat metal stock; said folded or turned edge closely contacting thestock the entire width of the' turned-over portion, forming blanks fromsuch stock in such manner that the closely folded or turned edge portionis cut entirely through and constitutes the writing tip end of such penor' pen point, and subsequently finishing the blank into pen contour andwriting condition.
